Abstract (en)

[origin: EP0581994A1] An improved receiver is described for a system for the transmission of information, inserted in a television signal, that is cyclically repeated, and is represented by a plurality of pages, each characterised by a number, and can be selected by the user, the receiver comprises memory means for memorising the numbers of the pages received. The principle characteristic consists in the fact that the situation of the pages effectively present in the transmission cycle is continually updated in memory by means of a procedure that provides for the continuous surveillance of the pages effectively transmitted. <IMAGE>
